• Studies composed over the last 2-9 years by the Global Change and Terrestrial Ecosystems core project of the International Geosphere-Biosphere Programme show that when heat around plants was increased, they started to grow faster and larger. When experimenting, temperatures in the range of 0.3-6.0°C increased soil respiration rates by 20% (with a 95% confidence interval of 18-22%), plant productivity was increased by 19% (with a 95% confidence interval of 15-23%), and net N mineralization rates by 46% (with a 95% confidence interval of 30-64%). This is what caused the plant to grow faster and larger, not including other geographic, climatic, or environmental variables that may have affected the growth of the plant.

    Soil respiration is a key ecosystem process that helps plants perform photosynthesis. When the soil respiration rates increased in the experiment, the plant was able preform the process more efficiently. Thus forth it was better able to release energy. This helped the plant grow and even caused it to grow faster.
    Plant productivity refers to the rate of biomass in an ecosystem. Biomass is material from living, or recently living organisms. These include wood, waste and hydrogen gas, among other things. When plant productivity is high, it means that the plant is larger and has more mass, such as having more leaves, blooms or growing taller and thicker than typical. This means that the plant is able to grow well.
    Mineralization is when the chemical compounds in plants decompose into plant-accessible forms, such as fertilizer. When plants die and break down, they become part of the soil , witch in turn helps other plans grow. This, overall, helps all plants grow better. When the mineralization rates rose by 46%, more decomposed plants were able to help the less mature plants. This natural fertilizer creates a cycle of plants, helping each one along the way. Because of this experiment, soil respiration, plant productivity, and mineralization rates rose. Researchers on this subject are 95% sure that these changes were due to the rise in temperature and not because of the geology of where they were planted. This does not prove that a global climate change will have the same effect. There are other variables that could change the way the plants grow, such as carbon dioxide (CO2) in the soil and the air, human land use, and pollutants, all of witch are a part of human caused climate change.
